SEABOBN E. MAYBERRY, OF BLAIR, TEXAS.

PUMP.

Application filed. June 6,

To all whomz't may concern:

Be it known that I, SnAnonN E. MAY- BERRY, a citizen of the United States of America, residing at Blair, in the county of Taylor and State of Texas, have invented new and useful Improvements in Pumps, of which the following is a specification.

The object of the invention is to provide simple and efficient means for securing a continuous flow from a deep well pump under conditions minimizing the strain upon the mechanism and the power required for actuating the same; and with this object in view the invention consists in a construction and combination of parts of which a preferred embodiment is shown in the ac companying drawings, wherein Figure 1 is an elevation of a pump mechanism embodying the invention.

Figure 2 is a plan view of the same.

Figure 3 is an end view thereof.

The mechanism contemplates the use of twin pump cylinders or tubes 10 having independent pump rods 11 which are respectively connected with ope-rating stems 12 fitted for sliding movement in guides 13 provided at the extremities of a cross head 14 supported by a framework or derrick 15 and receiving motion from a drive shaft 16 which is mounted in suitable bearings on said framework.

Any suitable means may be employed for communicating a continuous rotary motion to the drive shaft as for example gears 17 secured to said shaft and receiving motion from pinions 18 which are carried by the power shaft 19 fitted in the construction illustrated with a belt pulley 20 but adapted to be motor actuated either directly or indirectly as may be found most convenient under the conditions in which the apparatus is used. The connections between the drive shaft and the operating stems 12 consist of links 21 extending from wrist pins 22 on 1922. Serial No. 586,330.

plings 2 1 of which the transverse reinforced members 2 1 operate between upper and lower horizontal plates 25 and 26 carried by the frame or derrick, with the lower plate provided with guides 27 for the upper ends of the pump rods. The couplings 2 1 are detachably connected terminally with the pump rods and operating stems by means of suitable conventional forms of unions 28 to permit of detachment or replacement as conditions may require.

Having described the invention, what is claimed as new and useful is t,

A mechanism of the kind indicated comprising a supporting frame, reciprocatory rods disposed in adjacent relation and in parallelism and slidably engaged in guides for reciprocatory movement, a cross head transversely spanning the frame at the top and provided with terminal guides, operating rods slidably mounted in said guides, a transverse drive shaft carried by the frame below the cross head and operatively connected with the operating rods for communicating reciprocatory movement thereto, connections between the operating rods and the reciprocatory rods and consisting of elbow couplings terminally connected respectively with the same, and upper and lower plates carried by the frame between which the offset elements of said elbow couplings operate.

In testimony whereof he aflixes his signature.

SEABORN E. MAYBERRY.
